@sullybiker Yeah, I think the controversy mostly was about how the tunnel is dug under the sea. We never have huge disputes about tunnel digging since we only have mountains to bore through - even though it doesn't really make a difference.
@beni I took my kids on a holiday in 2004 where we spent a week in London then took the Eurostar to Paris for a week. I'd made a big fuss about travelling in a train under the sea but I guess I over-sold it and it was an anti-climax. London & Paris were cool though 😃
